<p>
The GtkTreeViewColumn object represents a visible column in a <a class="link" href="GtkTreeView.html" title="GtkTreeView"><span class="type">GtkTreeView</span></a> widget.
It allows to set properties of the column header, and functions as a holding pen for
the cell renderers which determine how the data in the column is displayed.
</p>
<p>
Please refer to the <a class="link" href="TreeWidget.html" title="Tree and List Widget Overview">tree widget conceptual overview</a>

they work together.
